cAqÄ«dah (Creed) is the foundation upon which all other Islamic activities are built. This is well enunciated in the Qur’Än, with supportive proofs in the Sunnah. However, cAqÄ«dah has been generating controversy among MufassirÅ«n (Qur’Änic Exegetes) of the early, medieval and modern periods. It is against this backdrop that this study aimed at studying selected theological issues in the Magnum Opus TafsÄ«r of ’al-’ImÄm ’al-’AlÅ«sī’s Rūḥu’l-MacÄnÄ«. The objectives of the study were to: (i) assess the view that ’al-’ImÄm ’al-’AlÅ«sÄ« is a controversial scholar; (ii) determine the quality and appropriateness of ’al-’ImÄm ’al-’AlÅ«sī’s argument and its consonance or otherwise with the fundamental principles of Islam; (iii) investigate ’al-’ImÄm ’al-’AlÅ«sī’s modes of treating theological matters; (iv) highlight the contributions of ’al-’ImÄm ’al-’AlÅ«sÄ« towards the correct understanding of the Qur’Än in general and theology in particular; (v) examine the differences in the classification of TafsÄ«r Rūḥu’l-MacÄnÄ«; and (vi) evaluate the discussion of ’al-’ImÄm ’al-’AlÅ«sÄ« on the convergent and divergent theological verses.rnrnrnThe study adopted historical and exegetical methods. Historical method was used in rendering the historical accounts of ’al-’ImÄm ’al-’AlÅ«sÄ«, while exegetical method assisted in analysing ’al-’ImÄm ’al-’AlÅ«sī’s discussion of verses with theological connotations in the light of Qur’Än and ḤadÄ«th.rnrnrnrnrnrnrnrnThe findings of this study were that: rnrni) ’al-’ImÄm ’al-’AlÅ«sÄ« is an objective scholar, as his Minhaj (method) is clear from his discussions on theological issues;rnii) ’al-’ImÄm ’al-’AlÅ«sÄ« always refers to the Salaf á¹¢Äliḥ, making his arguments to be of high quality and in accordance with the fundamental principles of Islam;rniii) ’al-’ImÄm ’al-’AlÅ«sī’s modes of treating theological matters were indicative of his mastery of exegesis for discussing theology-related verses clearly; rniv) theological divergences were not only borne out of philosophical thinking in defence of individual sect and lack of proper understanding of the Islamic texts, but also for lack of reference to the pristine Islam; rnv) TafsÄ«r Rūḥu’l-MacÄnÄ« is a class on its own for combining kinds of TafsÄ«r, a quality which seems rare in other TafsÄ«r books; rnvi) theological discussions of ’al-’ImÄm ’al-’AlÅ«sÄ« subsumed, to a large extent, the views of these Islamic sects: Sunnites, Shiites, Ashcarites and Muctazilites, including the Ṣūfiyyah; andrnvii) discussion on theological issues by the contemporary Muslims is predicated upon the stand of Salaf in order for theological differences to be resolvable.rnrnrnThe study concluded that Rūḥu’l-MacÄnÄ« is an exegetical book, which ranked among similar works by the renowned MufassirÅ«n, based on the understanding of the early predecessors and that theological differences are resolvable through TafsÄ«r if dissociated from individualism, sectarianism, shallow research, superciliousness and haste in giving Islamic verdict. The study, therefore, recommended a re-examination of the divergent theology-related issues based on the understanding of the pristine Islam that is free from extraneous philosophical thinking.
